Why are modern-day griots important to our understanding of the history of the mali empire?

Musician. The griot is a repository of oral tradition and is often seen as a societal leader due to his traditional position as an adviser to royal personages. As a result of the former of these two functions, he is sometimes also called a bard. According to Paul Oliver in his book Savannah Syncopators, "Though [the griot] has to know many traditional songs without error, he must also have the ability to extemporize on current events, chance incidents and the passing scene. His wit can be devastating and his knowledge of local history formidable". Although they are popularly known as "praise singers", griots may use their vocal expertise for gossip, satire, or political comment.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
